The Schrödinger Functional and Non-Perturbative Improvement

Abstract

After describing the Schrödinger functional for standard and improved gluon and quark actions we present results for the non-perturbative clover coefficients of the SW quark action coupled to the Wilson plaquette action for $\beta \ge 5.7$, as well as the Lüscher-Weisz one-loop tadpole improved gauge action, both in the quenched approximation.
